Moved src/ source code to src/qpid directory:
- allows rhm package to build consistently against checked-out or installed qpid. - consistent correspondence between source paths and C++ namespaces. - consistent use of #include <qpid/foo> in source and by users. - allows header files to split over multiple directories, e.g. separating generated code, separating public API from private files. git-svn-id: https://svn.apache.org/repos/asf/incubator/qpid/trunk@528668 13f79535-47bb-0310-9956-ffa450edef68
